The article evaluates the accurate material composition (chemical, mineralogical, as well as structural relation of gold with various minerals) and technological characteristics of the 2 technological ore sampling (weight 200-250 kg) representing relatively newly discovered Tulallar various gold-bearing deposits. According to the investigations this minerals might be related to the poor sulfide ore type composed of calgedony-quartz-kaolinite-pyrite represented by delicate gold-bearing and different oxidation level. According to their oxidation levels and material composition, one of the ore sample is character-ized by oxidation specific to the sulfide deposits, another one is semi-oxidation – composed zones. Based on this factor, it is recommended that deeper horizons of the deposit contains primary – sulfide gold bearing ores at the significant degree. To obtain the investigated ore, various technological method used in the gold-bearing ore industry, as well as gravitation, floata-tion and hydrometallurgy (cyanide leaching) had been assessed. Through test works carried out, it had been determined that for processing this ore the most efficient method and the method having the highest degree of separation of gold is sorption (syn-thetic resin) cyanide agitation leaching. This method being de-veloped under optimum laboratory conditions provided extrac-tion of 95-95,4% gold by means of synthetic resin (anionite).
